JAMES N. BONNELL, OF FORT HILL, PENNSYLVANIA.

BAIL-CHAIR.

Application filed January 7, 1910.

T 0 all whom it may concern:

Be it known that I, JAMns N. BONNELL, a citizen of the United States, residing at Fort Hill, in the county of Somerset, State of Pennsylvania, have invented certain new and useful Improvements in Rail-Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in rail braces and more particularly to that type of brace known as a railway chair.

One object of the invention is the provision of a chair provided with a brace lug having a perpendicular inner face to bear on the web of a rail and further provided with a recess or socket to receive the head of a fish-plate bolt, whereby the entire inner face of the brace lug will be permitted to bear on the rail web or fish-plate when a pair of the latter are employed.

With the above and other objects in view as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claim, it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification :--Figure 1 is a plan view of the device. Fig. 2 is a transverse sectional view of the same. Fig. 8 is a detailed perspective of a portion of the chair and showing the recess or socket on the inner face of the brace lug.

Similar numerals of reference are employed to designate corresponding parts throughout.

The chair consists essentially of a base plate designated by the numeral 5. This member is preferably of a single piece of metal substantially rectangular in marginal contour and cross section and designed to 'be secured by the usual spikes 6 to the upper face of a tie. The lower face of the base plate is provided with a plurality of longitudinal ribs 7, the edges of which are sharpened and are adapted to embed in the tie Specification of Letters Patent.

whereby accidental slipping is prevented. The length of the base plate 5 is considerably greater than the width of the base flange 8 of the rail, to be supported, so that when it is positioned as shown in Figs. 1 and 2, between the base flange 8 of the rail and cross tie its opposite ends will extend considerably beyond the opposite sides of the base flange 8 of the rail.

The type of rail shown is the well known T-shape including the tread flange 9 and web 10, and as shown in Fig. 1 the device is located at the meeting ends of a pair of such rails. It is well known that the usual method of' connecting the meeting ends of a pair of these rails consists in placing a pair of fishplates 11 and 12 on the opposite faces of their webs and securing the fish-plates to the webs by means of bolts and nuts 13 and 14.

Rising from the upper face of the base plate 5 is what will subsequently be termed a brace lug designated in general by the numeral 15. This brace lug is located adjacent one end of the base plate 5 and extends upwardly and inwardly to a point adjacent the central point of the base plate. As shown in the drawings the brace lug is formed integral with the base plate 5 and its inner end rises to a height corresponding approximately to the width of the rail web 10, so that when it is positioned as shown in Figs. 1 and 2 the inner end portion of its upper side will bear on the lower face of the tread flange 9 of the rail. Adjacent the lower side portion of the inner end of the. brace lug, an under-cut is made as shown at 16 in Fig. 3. This under-cut slants downwardly and corresponds to one half the width of the base flange 8 of the rail, so that when the parts are positioned as before described that portion of the base flange lying on one side of the rail web will be disposed in the under-cut 16, as clearly shown in Fig. 2. The inner end of the brace lug is designated by the numeral 17 and as shown in Fig. 3 this end is vertical so that when it is positioned as before described, its entire surface will bear on the adjacent side of the rail web. It frequently happens when positioning a device of this kind that the fish-plate bolts interfere and prevent the inner end of the brace lug from bearing on the web or fish-plate. In order to overcome this a socket or depression 18, is formed on the inner end of the brace lug and of sufficient size to receive an ordinary bolt head. The socket extends Well into the body of the brace lug and if desired may receive the nuts used for securing the bolts in the fish-plate. This may be done by positioning the device opposite to that shown in Fig. 2 and when so positioned it will be observed that the socket Will act as a lock for the nut and prevent the latter from turning.

It will be noted by referring to Fig. 2 that When the chair is in applied position the inner Wall of the socket formed in the brace lug engages the head of the bolt so that the accidental backing out of the bolt is positively prevented. By this construction the bolt head is held tightly up against the fish plate so that the danger of the bolts Working loose, due to the vibration of passing trains, is reduced to a minimum.

Thus it Will be seen that I have provided a device which is comparatively simple in structure, inexpensive to manufacture, enlbodying few parts and these so arranged that the danger of derangement Will be reduced to a minimum.

\Vhat I claim as new is A rail chair comprising a base plate having spike openings, and a brace lug mounted thereon having a. flat rail flange engaging face, said face being provided with a concave depression for receiving the fish plate bolt of the rail, the inner Wall of said depression being adapted to bear against the bolt and prevent accidental backing out thereof. 1

In testimony whereof, I afl ix my signature, in presence of two Witnesses.
